Closed Loop System???

[Terryz_]

Heard something abt a closed loop system for marine tank... I would like to know more abt it... Can someone explain more abt it... Thkz alot...

For a closed system a pump is used to generate current flow rather than a powerhead or tunze.

Additional piping is required to enable water to be drawn out from the main tank using the pump and pumped back into the tank.

The closed loop system is more presentable as the pump can be kept hidden unlike the powerhead. However, the closed loop system lacks the flexiblity of the powerhead in that the pipes are fixed.

It is just like ###### water from the tank to canister den pump back to tank like that huh...

Yep. Dont need a canister.

I am using Eheim 1262 to drive my closed loop.

A closed loop driven by one powerful pump does away with multiple powerheads in a tank.

It may reduce unsightliness and maybe even reduce heat transferred into the water.

Technically... a closed loop should not enter into a filtration canister.

hi den where you place your edhim pump ?? is it beside the sump or inside the tank and hide between the live rock ...

That mean drill hole in the tank then fit the pipes and connect to pump and voila... A closed loop huh...
